Hello,
I am using heatmap.2 from the gplots library to plot a small symmetrical
matrix.
This is the command:
heatmap.2(tempHeat,symm=T,trace="none",cexRow=0.7,cexCol=0.7,col="redgreen",density.info="none")
I have a couple of questions:
1) The range is from -0.2 to 0.4 and the colour scheme I am using is
redgreen. What I would like is that a zero value to be black, 0.4
strong green and -0.2 red. Is this possible? At the moment around 0.1
is black.
2) Is it possible to overlay text on the squares of colour? How ould
one go about doing that.
I am happy to use another heatmap function if ti would be better. I am
not using the original heatmap as it does not provide a colour key.
Thanks
Dan
